问题 I need to update millions of rows as part of my next release, but doing so fills the transaction log and fails. I have a few ideas but I'm not a SQL expert so I'm sure there will be gotchas that I'm not aware of.

(I've thought about writing a loop with a try-catch with WAITFOR DELAY '00:15:00' in the catch
